you can have two dependent variables because you need two test groups with an independent variable in each so you can make sure that they are different in each because you don't want the same result in a science experiment

Why is it important to test only one variable at a time during a experiment?

If you test only one variable then you know that the difference in the experimental and control setup is that one independent variable. If you test more than one you will not know which one made the difference.


Has only one independent variable?

An experiment with only one independent variable is called a one-way experiment. This means that the effect on the dependent variable is attributed to changes in only one factor. This design helps to determine the specific impact of that variable on the outcome of interest.


Why is it important for an experiment to only have one indepedent variable?

because in certain experiments you need an accurate independent variable so your conulsion could be accurate

What variable is the only one that purposely changed to test a hypothesis in an experiment?

Independent variable : )


Why can you have only one variable in a experiment?

Actually, you have two - dependent and independent. But, you only have one variable because otherwise the answer wouldn't be accurate if you had more than one variable.


The independent variable?

The independent variable is the one that is changing


Can a valid experiment have only one independent variable?

Yes, a valid experiment can have only one independent variable. In fact, many experiments are designed with a single independent variable to investigate its specific impact on the dependent variable while controlling for other factors. This helps researchers to isolate the effect of that variable on the outcome of the experiment.


Does the independent or dependent variable change?

The Independent variable is the one you control. The dependent variable is controlled by the Independent Variable.


What is the factor of interest in an experiment called?

The independent variable. Any variable that is kept the same is a constant variable (although it is a contradiction in terms); any variable - usually only one - that depends on the independent variable is a dependent variable.


Identify the independent variable?

What is one independent variable?

Time is often an independent variable.
